Kraken vs Coinbase.

Which is safer? — the sourced record

These two look similar on paper — both US-rooted, both MiCAR-licensed in 2025 (Kraken via the Central Bank of Ireland, announced 2025-06-25; Coinbase via Luxembourg’s CSSF, announced 2025-06-20), and both saw their SEC cases dismissed with prejudice in early 2025. The differences live one layer down.

Proof of reserves: Kraken runs a quarterly auditor-assisted Merkle-tree program with per-client self-verification (~$21.5B of client assets verified in March 2025). Coinbase runs no Merkle-tree proof-of-reserves at all — it substitutes public-company assurance: an audited annual 10-K and quarterly reviews. Whether an audited balance sheet or a client-verifiable Merkle proof is the stronger form of evidence is exactly the kind of question our methodology page unpacks; the component table above shows how each is scored.

Incident records: Kraken (founded 2011) has no platform-wide withdrawal halt documented in 36 months of public status history; its June 2024 zero-day bug (~$3M withdrawn by security researchers) was patched in 47 minutes with funds returned, and Australia’s court ordered AUD 8M over a margin product in December 2024. Coinbase’s recent record is heavier: a May 2025 insider data breach affecting 69,461 customers (bribed support contractors; no funds or passwords; estimated $180–400M cost per its SEC 8-K), an ~8-hour halt of trading and withdrawals during the 2026-05-07 AWS thermal event, ~3 hours of degraded service in the 2025-10-20 AWS outage, and a £3.5M UK FCA fine in July 2024. Every entry is dated and sourced; the live scores above apply 24-month decay to all of it.

Which is cheaper? — what stays true between snapshots

The live cards above carry the published base-tier fees and the measured all-in cost of the same $1,000 BTC buy — the spread is re-measured continuously. Structurally: Kraken publishes a fixed BTC withdrawal fee (shown live above); Coinbase publishes no fixed schedule and passes the prevailing network fee through at withdrawal time, so its totals on this page honestly exclude withdrawal.

Both venues carry a curated convenience markup worth knowing about: Coinbase’s simple-buy/convert flow at roughly 50–200 bps and Kraken’s Instant Buy at roughly 150–240 bps (both curated ranges, verified 2026-06-10). Our table prices the spot orderbook on both — trading spot avoids the markup on either venue.
